An electronic source of pharmacy/medical encounter information will be used to assess the demographics and other characteristics of the subjects prescribed FTC/TDF or its components in a prospective fashion. The data provider will supply all the de-identified information regarding each visit/interaction that the subject has had with the health system and all the diagnoses and medications that the UI has had prospectively and retrospectively for the length of time captured by the source selected.

200 physicians who prescribe FTC/TDF for a PrEP indication will be sampled from the same source.

Demographics (including age, gender and if available, race and ethnicity) and clinical characteristics (including diagnoses, procedures, and laboratory test results) will be summarized by 1) exposure group and 2) overall using descriptive statistics (sample size, mean, standard deviation, median, interquartile range, minimum and maximum) for continuous data, and by the number of participants for categorical data; age will be calculated as age in years at exposure.

Demographics (including gender, medical degree, medical specialty, number of years in medical practice, and setting of care) of prescribers of FTC/TDF for a PrEP indication will be summarized using descriptive statistics (sample size, mean, standard deviation, median, interquartile range, minimum and maximum) for continuous data and by the number prescribers for categorical data.
